Competing T=0 and T=1 structures in the N=Z nucleus 6231Ga

Abstract

The low-lying levels in the odd-odd N=Z nucleus 62Ga have been identified for the first time. These data reveal a cascade of stretched-E2 transitions based on a T=0, 1+ bandhead which decays directly to the T=1, 0+ ground state. The observed levels are interpreted in the context of theshell model, using as a basis, the pf5/2g9/2 orbits with a 56Ni core.
